MANIFOLD-PAPER.

SPECIFICATION forming part of Letters Patent No. 665,622, dated January8, 1901.

Application filed October 23, 1899. RenewedNovember 19, 190.0. SerialNo. 37,051. (Specimens.)

io ord i nary paper having one or both sides coated with carbon, andparticularly to the kind of carbon or coloring-matter applied to thepaper, so as to make a concrete article of man ufacture, all of whichwill be more fully herer inafter set forth.

The principal object of my invention is to provide a simple, economical,and efficient article of manufacture known as manifold-paper having asurface or surfaces of hardened 2o finished carbon; and the inventionconsists in the article of manufacture hereinafter described andclaimed.

In the accompanying drawings, Figure lis a plan view of a piece ofmanifold-paper constructed in accordance with my improvements, and Fig.2 a broken side elevation of the same.

In the art to which this invention relates it is well known thatY theordinary manifold or 3c carbon paper as used in commerce is provided onone or both of its surfaces with a coating of carbon or othercoloring-matter, and it is also known that the coloring-matter isapplied to the paper in a soft condition and remains thereon in a softcondition, so that when the operator handles such paper thecoloringmatter comes off, to the detriment of the paper and to theannoyance of the operator. The principal object of my invention, there-4o fore, is to provide an article of manufacture known asmanifold-paper7 with a hardened surface or coating of carbon orequivalent coloring-matter, all of which will more fully hereinafterappear.

In constructing my improvement I take a sheet of paper A-and preferablyapply a coloring-matter B thereto by means of a roll or othercolor-applying mechanism, and after such coloring-matter has beenapplied thereto 5o it is hardened and finished by means of mechanism,preferably roll and polishing mechanism, so that the coloring-matter issubstantially evenly and uniformly applied to and spread over thesurface and afterward hardened and finished. This paper I have foundfrom experimental use to be very satisfactory in that, first, handlingof the paper does not injure it to any appreciable extent, and, second,the coloring-matter does not come olf, to the annoyance or discomfort ofthe operator.

The article of manufacture may be iliade by various kinds ofmachinery-such, for instance, as I have described in connection with myapplication for Letters Patent of the United States, Serial No. 671,281,tiled February 23, 1898, to which application I respectfully refer thosewho desire a complete description 0f one class of machine formanufacturing the article. In this class of machines the coloring-matteris applied to the paper in the shape of a cake of the consistency ofsoap. It can then by means of a roll be evenly distributed on the paper,and after the color has been applied to the paper by roll orequivalentmechanism it can be spread thereon either by vibrating platensor irons or distributed by means of wing polishers and afterwardhardened on the surface by means of rolls or polishers. The finishing orpolishing of the paper, which also removes all surplus material, can beaccomplished by means of rapidly-rotating wing polishers.

The cakeof coloring material is formed as follows: A quantity of wax andtallow is taken and broken up in a finely-divided condition and aquantity of finely-divided carbon mixed therewith. The coloring materialcan be either lampblack or Prussian blue. After mixing the compositionis melted and poured into molds, which will form cakes about an inchthick and of any desired length or width. I, however, prefer to use acake twenty inches long and from eight to twelve inches wide. Vhen coolthe cakes should be about the consistency of hard soap.

The use to which this invention is principally applicable is inconnection with telegraph-blanks, train-orders, letter-heads, and otherblanks or forms which have printed matter upon one side of a sheet ofpaper which is adapted to be written upon with the usual appliances,such as a pen or pencil or IOO stylus or a type-writing machine, and areformed and printed in duplicate or triplicate, as may be desirable. Whenin duplicate, the backof one blank or form is provided with a surface ofhardened carbon, as above described, and when in triplicate the firstand second blanks are provided with the surface of hardened carbon onthe backs thereof, as above described,so that an impression orimprintmade on t-he face of the first of these blanks is copied on the adjacentregistering blanks or sheets Without the use of interleafingcarbon-sheets- The invention is also applicable for many other purposes,such as stock-books, record-books, invoice-books, bills of lading,shipping-blanks, and the like, as Will be readily appreciated by thoseskilled in the art who have carefully read the foregoing.

1. As a new article of manufacture, a manifold-paper provided with asurface of hardened carbon or similar coloring material, substantiallyas described.

2. As a new article of manufacture, a manifold-paper with a surface ofcarbon or other equivalent coloring` material hardened and polished,substantially as described.

8. As a new article of manufacture, a inanifold-paper adapted to beWritten upon provided with a printed form or heading on one side and asurface of hardened coloring material on the opposite side, whereby amanifold copy or impression can be taken on an adjacent sheet Withoutthe use of interleafing carbon, substantially as described.

4;. Asa new article of manufacture, a inanifold-paper adapted to beWritten upon on one side and provided with a surface of hardenedcoloring,r material on the other side, whereby a manifold copy, imprintor impression can be taken on an adjacent sheet Without the use ofinterleaing carbon, substantially as described.
